This paper describes a method to determine the inductance gradient, L{prime}, for railguns from the measured current, measured mass of the projectile, and the inbore projectile position taken from the B-Dot coils. The procedure used is to fit the measured position data to a derived function using the method of least squares. The procedure was used on several shots for two configurations of railguns, the square bore and the parallel configuration railgun (parallel gun). The values of L{prime} obtained were within a few percent of the calculated values.
